Improvement in sights for fire-arms



UNITED STATES PATENT OFFICE.

IMPROVEMENT IN SIGHTS FOR FIRE-ARMS.

Specification forming part of Lctters Patent No. 37.782, dated February 24, 1863.

To all whom, it may concern:

Be it known that I, JAMEs WARNER, of

" Springfield, in the county of Hampden and State of Massachusetts, have invented a new and useful Improvement in Three-Leaved Sights forFire-Arms, and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a plan of a three-leaved sight constructed according to my invention. Fig. 2 is a vertical section of the same. Fig. 3 is a plan of the base of the sight. Fig. 4 is a plan of the leaf.

Similar letters of reference indicate corresponding parts in the several figures.

The object of my invention is to provide for the convenient adjustment of the joint of the sight and the tightening of the same after it has become loose by wear; and to this end it consists in slitting the base and one of the leaves of the sight in such a manner, and soapplying the j oint-pin in combination with them, that the several parts of the joint can all be tightened up simultaneously and uniformly by 13 is the longest or back leaf of the sight, made in the usual mannerwith legs 00 to form portions of the joint and fitted between the cheeks a a of the base. This leaf has a narrow slit, 9, cut in it from its lower or front end, which is next the j oint. About half-way to the opposite end, de is an angle-piece, constituting the shortest and middle leaves of the sight,

constructed and fitted between the lugs c c of the longest leaf in the usual manner.

f is the joint-pin, screwed at its end, passing through one of the checks (1 a, through the lugs c c, and the elbow of the angle-piece de, and screwing into a tapped holein the other cheek. By screwing up this pin the cheeks a a are tightened upon the lugs c 0, and the said lugs tightened upon the piece de, and thus the whole joint is tightened to prevent the leaves from working with more than a desirable degree of freedom, the slits b and g permitting such action of the pin by providing for the adjustment of the cheeks and lugs.

WVhat I claim as my invention, and desire to I secure by Letters Patent, is

The combination of the screwed-joint pin, the slit 1) in the base A, and the slit 9 in the leaf B, substantially as herein described, whereby the screwing up of the pin is caused to tighten all parts of the joint.

JAMES WARNER.
